SeaTalk MCP Server

This server provides Model Context Protocol (MCP) tools to interact with the SeaTalk API. It enables AI assistants to send and retrieve messages, access employee information, and interact with group chats via SeaTalk.

Setup

1. Install dependencies:

   npm install

2. Create a .env file with your SeaTalk credentials:

   SEATALK_APP_ID=your_app_id
   SEATALK_APP_SECRET=your_app_secret

3. Build the server:

   npm run build

4. Start the server:

   npm start

Installation

You can install this package via npm:

# Install globally
npm install -g seatalk-mcp-server

# Or use directly with npx (auto-install without prompts)
npx -y seatalk-mcp-server

NPX Usage

This package can be used directly via npx without installing it globally. The -y flag automatically accepts installation prompts for seamless automation.

Configuration in MCP Settings

Configure the SeaTalk server in your MCP settings by providing the required environment variables:

{
  "mcpServers": {
    "seatalk-mcp-server": {
      "command": "npx",
      "args": ["-y", "seatalk-mcp-server"],
      "env": {
        "SEATALK_APP_ID": "your_app_id_here",
        "SEATALK_APP_SECRET": "your_app_secret_here"
      },
      "disabled": false
    }
  }
}

Required environment variables:

• SEATALK_APP_ID: Your SeaTalk application ID
• SEATALK_APP_SECRET: Your SeaTalk application secret

Using with Cursor or other MCP-compatible tools

After configuring the server in your MCP settings, SeaTalk tools will be available for use in Cursor or other MCP-compatible environments.

Local Development & Manual Build

If you prefer to clone the repository and build the server yourself, follow these steps:

Prerequisites

• Node.js 16.0.0 or higher
• npm or yarn package manager

Clone and Build

1. Clone the repository:

   git clone https://github.com/muhammad-iqbal/seatalk-mcp-server.git
   cd seatalk-mcp-server/seatalk-server

2. Install dependencies:

   npm install

3. Create environment configuration:

   # Create .env file with your credentials
   echo "SEATALK_APP_ID=your_app_id_here" > .env
   echo "SEATALK_APP_SECRET=your_app_secret_here" >> .env

4. Build the project:

   npm run build

5. Run the server directly:

   node build/index.js

Configuration in MCP Settings (Local Build)

When using the locally built version, configure your MCP settings to point to the built file:

{
  "mcpServers": {
    "seatalk-mcp-server": {
      "command": "node",
      "args": ["/path/to/your/seatalk-mcp-server/seatalk-server/build/index.js"],
      "env": {
        "SEATALK_APP_ID": "your_app_id_here",
        "SEATALK_APP_SECRET": "your_app_secret_here"
      },
      "disabled": false
    }
  }
}

Note: Replace /path/to/your/seatalk-mcp-server/seatalk-server/build/index.js with the actual absolute path to your built index.js file.

Development Workflow

For active development, you can use the watch mode:

# Build and watch for changes
npm run watch

# In another terminal, run the server
node build/index.js

This approach is useful for:

• Contributing to the project
• Customizing the server for specific needs
• Testing unreleased features
• Running in environments where npx is not available
